BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention are described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram describing a process between a safety service system and a guardian/ward terminal according to an embodiment of the present invention.

Embodiments of the present invention provide an environment for monitoring and managing a ward. To this end, a safety service system 120 may collect location information of a ward and image information of the ward, such as a photo and a moving picture, from a ward terminal 110. Here, a small terminal embedded with a global positioning system (GPS) and a camera may be used as the ward terminal 110 in order to provide location information and image information from a ward side to the safety service system 120. The safety service system 120 may support a service environment in which a guardian may monitor a current state of the ward without restrictions on a time and an occasion based on the location information and the image information collected from the ward terminal 110. In particular, the safety service system 120 may provide a safety service based on a location based service (LBS). Here, the safety service may be provided in a web/wap service form through a service page on the safety service system 120, or may be provided as a service-only application. The service-only application may include a personal computer (PC) based program or a mobile-only application. That is, the guardian may connect to a service screen, for example, a service page screen or an application execution screen, associated with a safety service using a communication terminal (hereinafter, a guardian terminal) 130 accessible to the safety service system 120, and may monitor an emergency situation of the ward through the service screen. Here, in response to a request of the guardian or an occurrence of a danger to the ward, the safety service system 120 may provide the collected location information and image information to the guardian terminal 130. Further, in response to a request of the guardian or an SOS dispatch request of the ward, the safety service system 120 may transfer location information and image information of the ward to a security company (not shown) and accordingly, a security agent may directly move to a corresponding location and thereby handle and cope with an emergency situation of the ward.

Initially, a configuration and an operation of a ward terminal will be described in detail with reference to FIG. 2. FIG. 2 is a block diagram illustrating a ward terminal 200 configured to provide a location and an image according to an embodiment of the present invention.

Referring to FIG. 2, the ward terminal 200 according to an embodiment may include a location calculator 210, a camera unit 220, a communication unit 230, an input unit 240, and an impact detector 250.

The location calculator 210 may be configured to calculate location information indicating a current location of a ward. Here, the location calculator 210 may calculate the current location of the ward using at least one of a GPS measurement method and a mobile communication base station (that is, a cell base station) measurement method. A location value and information on a measurement method used to calculate a corresponding location may be included in the location information.

The camera unit 210 may provide a function of photographing a focused image. The ward may hold the camera unit 220 to be externally exposed, so that the ward terminal 200 may capture a peripheral image of the ward. The camera unit 220 may photograph a peripheral image of the ward. In this instance, the camera unit 220 may take at least one photo at predetermined time intervals or may take a moving picture during a predetermined period of time based on a setting environment and may use the same as image information of the ward.

The input unit 240 may be configured to receive an alert signal from the ward. In a case in which an emergency situation occurs, the ward may generate the alert signal by manipulating the input unit 240 with the intention of notifying the guardian about the occurrence of the emergency situation.

The impact detector 250 may be configured to detect a level of impact based on an external impact applied to the ward terminal 200. Here, the impact detector 250 may include an impact detection sensor, such as an acceleration sensor, to detect a level of impact applied to the ward terminal 200.

The communication unit 230 may be configured to transmit location information obtained from the location calculator 210 and image information obtained from the camera unit 220 to a safety service system. As an example, in response to a request of the safety service system, the communication unit 230 may transmit location information and image information to the safety service system. As another example, in response to an alert signal input from the ward via the input unit 240, the communication unit 230 may detect the alert signal as an abnormal signal associated with the ward and thereby transmit location information and image information to the safety service system. As another example, when a level of impact detected by the impact detector 250 exceeds a threshold, the communication unit 230 may detect the above impact as an abnormal signal associated with the ward and thereby may transmit location information and image information to the safety service system.

According to the above configuration, the ward terminal 200 may collect location information and image information associated with the ward and may transmit the collected location information and image information to the safety service system in response to an abnormal signal being detected or a request of the safety service system. Here, the location information and the image information may be collected at the safety service system and may be used as information for a safety service.
